Evaluation of post-annealing-induced defects dynamic behaviors on 90nm In-halo nMOSFETs with low frequency noise and charge pumping measuring techniques
Yean-Kuen Fang

As ULSI (ultra large scale integration) scales down, the threshold voltage shift ΔVtL caused by short channel effect (SCE) becomes serious as shown in Fig.1, especially for nano regime, ...

Effect of soil texture on the propagation and attenuation of acoustic wave at unsaturated conditions
Wei-Cheng Lo

1. RESEARCH OBJECTIVES
Over the past decades, the increasing scientific focus on the mechanical behavior of a fluid-containing porous medium has generated great interest in connecting the velocity and dissipation of acoustic waves to the hydrological properties of the shallow subsurface, ...

Acetaldehyde Involvement in Positive and Negative Alcohol Expectancies in Han Chinese Persons with Alcoholism
Ru-Band Lu

Studies have revealed that the enzyme encoded by ALDH2*1 is an active form, whereas that encoded by ALDH2*2 is an inactive form 10. Thus, people with a ALDH2*1/*2 or ALDH2*2/*2 genotype catabolizes acetaldehyde at a slower rate or to the extent of not at all. ...

Optically switchable biphotonic gratings based on dye-doped cholesteric liquid crystal films
C.-R. Lee

Dye material–doped liquid crystals (LCs) have received considerable interest in the development of all optically controllable devices due to their large birefringence and ability to be flexibly controlled through interaction with photoexcited dyes. ...

Comprehensive Evaluation Criteria for English Learning Websites Using Expert Validity Surveys
Y.-T. C. Yang

1. Introduction
Nowadays, the world is a global village where people communicate with each other through a common language which has been recognized as English, a universal language in the international community. Internet World Stats in 2007 states that the major language used on the Internet is English, ...
